The title compound, C(10)H(12)O(2), was synthesized as a candidate for further functionalization. The asymmetric unit comprises two independent mol-ecules, both of which are situated on a center of symmetry. Both mol-ecules are involved in a network of hydrogen bonding, with each alcohol group participating in one hydrogen bond as a donor and in a second hydrogen bond as an acceptor.

The title compound, C(10)H(8)O(2), is a precursor to an unusual bis-homoaromatic dication and to heterodiamantanes and other oxa-cage compounds. Two independent mol-ecules, each of which is situated on a center of symmetry, comprise the unit cell. Both mol-ecules are in nearly identical chair conformations.

Strained azirinium ylides derived from 2H-azirines and α-diazoketones under Rh(II)-catalysis can undergo either irreversible ring opening across the N-C2 bond to 2-azabuta-1,3-dienes that further cyclize to 2H-1,4-oxazines or reversibly undergo a 1,5-cyclization to dihydroazireno[2,1-b]oxazoles. Dihydroazireno[2,1-b]oxazoles derived from 3-aryl-2H-azirines and 3-diazoacetylacetone or ethyl diaz...

The title tricyclic diene, C(24)H(22)Cl(2), is the product of thermal ring-opening of a corresponding basketane (penta-cyclo-[4.4.0.0(2,5).0(3,8).0(4,7)]deca-ne) derivative. The cyclo-butene ring is planar to within 0.0032 (12) Å and its geometry is normal. The two 4-chloro-phenyl groups are oriented in an approximately face-to-face conformation with a dihedral angle of 44.14 (6)° between them....
